Abstract

The mechanically actuated brake (10) comprises a laterally movable sleeve housing (22) which is attached by means of slots (24) and connections (26) with the support plate (28). A mechanical actuator and adjuster mechanism (40) has parts (42, 48) received within a longitudinal through opening (27) of the housing (22), a first part (42) of the mechanism (40) abutting one brake shoe end (20) while a second part (48) of the mechanism (40) abuts the other brake shoe end (18). A lever (50) for service brake operation is attached pivotably by a connection pin (30) with the housing (22) and extends through a transverse through opening (29) of the housing (22). The lever (50) is received within a slot (49) of the second part (48) of the mechanism (40), and includes an actuating arm (57) which extends through the housing (22) and is engageable with an actuating arm (66) of a pawl (60) that actuates the adjuster portion of the mechanism (40). The pin connection (30) also mounts rotatably the pawl (60) to the housing (22). The pawl (60) includes a spring support flap (67) which receives one end of aspring (70) attached to the one brake shoe end (20).
